These tables describe the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. You may pay other fees (including on Class R6 and Advisor Class shares), such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below. You may qualify for sales charge discounts in Class A if you and your family invest, or agree to invest in the future, at least $25,000 in Franklin Templeton funds and certain other funds distributed through Franklin Distributors, LLC, the Fund’s distributor. More information about these and other discounts is available from your financial professional and under “Your Account” on page 61 in the Fund’s Prospectus and under “Buying and Selling Shares” on page 61 of the Fund’s Statement of Additional Information. In addition, more information about sales charge discounts and waivers for purchases of shares through specific financial intermediaries is set forth in Appendix A – “Intermediary Sales Charge Discounts and Waivers” to the Fund’s prospectus.

Portfolio Turnover [Text Block] oef_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 27.09% of the average value of its portfolio.

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of the period. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The Example reflects adjustments made to the Fund's operating expenses due to the fee waivers and/or expense reimbursements by management for the 1 Year numbers only. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy Narrative [Text Block] oef_StrategyNarrativeTextBlock

Under normal market conditions, the Fund invests at least 80% of its net assets in the equity and debt securities of companies in the natural resources sector. The Fund predominantly invests in equity securities. For the Fund’s investment purposes, the natural resources sector includes companies that own, produce, refine, process, transport and market natural resources and companies that provide related services. The sector includes, for example, the following industries: integrated oil, oil and gas exploration and production, gold and other precious metals, steel and iron ore production, energy services and technology, energy transition, base metal production, forest products, farming products, paper products, chemicals, building materials, coal, alternative energy and environmental services. In addition to its investments in companies in the natural resources sector, the Fund may also invest up to 20% of its net assets in equity or debt securities of any type of issuer.

The Fund may invest a significant portion of its assets in smaller capitalization companies, which are generally companies with market capitalizations of less than $2 billion at the time of the Fund’s investment. The Fund anticipates that, under normal conditions, it will invest more of its assets in U.S. securities than in securities of any other single country. The Fund may also buy American Depositary Receipts.

The Fund also may attempt, from time to time, to hedge (protect) against market risk or to generate income for the Fund by buying and selling put and call options on equity securities and equity security indices. The Fund’s investments in derivative instruments and other investments that provide exposure to the investment focus indicated in the Fund’s 80% policy, or that provide exposure to one or more market risk factors associated with the investment focus indicated in the Fund’s name, are included in the Fund’s 80% basket.

The investment manager is a research driven, fundamental investor, pursuing a growth strategy. As a "bottom-up" investor focusing primarily on individual securities, the investment manager seeks companies that have identifiable drivers of future earnings growth and that present, in the investment manager's opinion, the best trade-off between that potential earnings growth, business and financial risk, and valuation. Also, in seeking sustainable growth characteristics, the investment manager looks for companies that it believes can produce sustainable earnings growth and cash flow growth or the potential to generate income.

Principal Risks

You could lose money by investing in the Fund. Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed by, any bank, and are not

insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. government.

FRANKLIN NATURAL RESOURCES FUND | Natural Resources Focus  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

Natural Resources Focus: The securities of companies in the natural resources sector may experience more price volatility than securities of companies in other industries. Some of the commodities used as raw materials or produced by these companies are subject to broad price fluctuations as a result of industry wide supply and demand factors. In addition, companies in the natural resources sector may be subject to special risks associated with natural or man-made disasters. Natural resources companies also can be significantly affected by events relating to international political and economic developments, energy conservation, the success of exploration projects, commodity prices, and tax and other government regulations.
FRANKLIN NATURAL RESOURCES FUND | Concentration  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

Concentration: To the extent the Fund concentrates in a specific industry, a group of industries, sector or type of investment, the Fund will carry much greater risks of adverse developments and price movements in such industries, sectors or investments than a fund that invests in a wider variety of industries, sectors or investments. There is also the risk that the Fund will perform poorly during a slump in demand for securities of companies in such industries or sectors.
FRANKLIN NATURAL RESOURCES FUND | Small Capitalization Companies  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

Small Capitalization Companies: Securities issued by small capitalization companies may be more volatile in price than those of larger companies and may involve substantial risks. Such risks may include greater sensitivity to economic conditions, less certain growth prospects, lack of depth of management and funds for growth and development, and limited or less developed product lines and markets. In addition, small capitalization companies may be particularly affected by interest rate increases, as they may find it more difficult to borrow money to continue or expand operations, or may have difficulty in repaying any loans. The markets for securities issued by small capitalization companies also tend to be less liquid than the markets for securities issued by larger companies.

FRANKLIN NATURAL RESOURCES FUND | Market  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

Market: The market values of securities or other investments owned by the Fund will go up or down, sometimes rapidly or unpredictably. The market value of a security or other investment may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all investments. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise. In addition, the value of the Fund’s investments may go up or down due to general market or other conditions that are not specifically related to a particular issuer, such as: real or perceived adverse economic changes, including widespread liquidity issues and defaults in one or more industries; changes in interest, inflation or exchange rates; unexpected natural and man-made world events, such as diseases or disasters; financial, political or social disruptions, including terrorism and war; and U.S. trade disputes or other disputes with specific countries that could result in additional

tariffs, trade barriers and/or investment restrictions in certain securities in those countries. Any of these conditions can adversely affect the economic prospects of many companies, sectors, nations, regions and the market in general, in ways that cannot necessarily be foreseen.

Ongoing or threatened armed conflicts throughout the world have caused and could continue to cause significant market disruptions and volatility. The hostilities and sanctions resulting from those hostilities could have a significant adverse impact on certain investments of the Fund as well as the Fund’s performance and liquidity.

Stock prices tend to go up and down more dramatically than those of debt securities. A slower-growth or recessionary economic environment could have an adverse effect on the prices of the various stocks held by the Fund.
FRANKLIN NATURAL RESOURCES FUND | Growth Style Investing  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

Growth Style Investing: Growth stock prices reflect projections of future earnings or revenues, and can, therefore, fall dramatically if the company fails to meet those projections. Growth stocks may be more expensive relative to their current earnings or assets compared to value or other stocks, and if earnings growth expectations moderate, their valuations may return to more typical norms, causing their stock prices to fall. Prices of these companies’ securities may be more volatile than other securities, particularly over the short term. In addition, investment styles can go in and out of favor, which could cause additional volatility in the prices of the Fund’s portfolio holdings.
FRANKLIN NATURAL RESOURCES FUND | Foreign Securities (non-U.S.)  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

Foreign Securities (non-U.S.): Investing in foreign securities typically involves different risks than investing in U.S. securities, including risks related to currency exchange rates and policies, country or government specific issues, less favorable trading practices or regulation and greater price volatility. Certain of these risks also may apply to securities of U.S. companies with significant foreign operations. The risks of investing in foreign securities are typically greater in less developed or emerging market countries.
FRANKLIN NATURAL RESOURCES FUND | Derivative Instruments  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

Derivative Instruments: The performance of derivative instruments depends largely on the performance of an underlying instrument, such as a currency, security, interest rate or index, and such instruments often have risks similar to their underlying instrument, in addition to other risks. Derivative instruments involve costs and can create economic leverage in the Fund's portfolio which may result in significant volatility and cause the Fund to participate in losses (as well as gains) in an amount that exceeds the Fund's initial investment. Other risks include illiquidity, mispricing or improper valuation of the derivative instrument, and imperfect correlation between the value of the derivative and the underlying instrument so that the Fund may not realize the intended benefits. When a derivative is used for hedging, the change in value of the derivative may also not correlate specifically with the currency, security, interest rate or other risk being hedged. With over-the-

counter derivatives, there is the risk that the other party to the transaction will fail to perform.
FRANKLIN NATURAL RESOURCES FUND | Management  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

Management: The Fund is subject to management risk because it is an actively managed investment portfolio. The Fund's investment manager applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these decisions will produce the desired results.

As an actively managed investment portfolio, the Fund’s investments do not track its benchmark. Overweighting investments in an industry or group of industries relative to the Fund’s benchmark increases the risk that the Fund will underperform its benchmark because a general decline in the prices of stocks in that industry or group of industries will affect the Fund to a greater extent than its benchmark. Price declines may result from factors that adversely affect a particular industry or group of industries, such as labor shortages or increased production costs, competitive conditions, or negative investor perceptions. Conversely, if the Fund underweights its investment in an industry or group of industries relative to the Fund’s benchmark, the Fund will participate in any general increase in the prices of stocks in that industry or group of industries to a lesser extent than the Fund’s benchmark.
FRANKLIN NATURAL RESOURCES FUND | Cybersecurity  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

Cybersecurity: Cybersecurity incidents, both intentional and unintentional, may allow an unauthorized party to gain access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, cause the Fund, the investment manager, and/or their service providers (including, but not limited to, Fund accountants, custodians, sub-custodians, transfer agents and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The investment manager has limited ability to prevent or mitigate cybersecurity incidents affecting third party service providers, and such third party service providers may have limited indemnification obligations to the Fund or the investment manager. Cybersecurity incidents may result in financial losses to the Fund and its shareholders, and substantial costs may be incurred in an effort to prevent or mitigate future cybersecurity incidents. Issuers of securities in which the Fund invests are also subject to cybersecurity risks, and the value of these securities could decline if the issuers experience cybersecurity incidents.

Because technology is frequently changing (including the development of artificial intelligence and machine learning), new ways to carry out cyber attacks are always developing. Therefore, there is a chance that some risks have not been identified or prepared for, or that an attack may not be detected, which puts limitations on the Fund's ability to plan for or respond to a cyber attack. Like other funds and business enterprises, the Fund, the investment manager, and their service providers are subject to the risk of cyber incidents occurring from time to time. The rapid development and increasingly widespread use of artificial intelligence

technologies could increase the effectiveness of cyber attacks and exacerbate the risks.

There is a 1% contingent deferred sales charge that applies to investments of $1 Million or more (see "Investments of $1 Million or More" under "Choosing a Share Class") and purchases by certain retirement plans without an initial sales charge on shares sold within 18 months of purchase.
[2] The investment manager has agreed to reduce its fees to reflect reduced services resulting from the Fund’s investments in Franklin Templeton affiliated funds. In addition, the transfer agency fees on Class R6 shares of the Fund have been capped so that transfer agency fees for that class do not exceed 0.03%. These contractual arrangements are expected to continue until August 31, 2027. During the terms, the fee waiver and expense reimbursement agreements may not be terminated or amended without approval of the board of trustees except to add series or classes, to reflect the extension of termination dates or to lower the waiver and expense limitation (which would result in lower fees for shareholders).
